There are siblings of $χ$ which are permutations for $n$ even

Björn Kriepke, Gohar Kyureghyan

Let $1$ be the all-one vector and $⊙$ denote the component-wise multiplication of two vectors in $F_{2}^{n}$ . We study the vector space $Γ_{n}$ over $F_{2}$ generated b…

Image sets of perfectly nonlinear maps

Lukas Kölsch, Björn Kriepke, Gohar M. Kyureghyan

We consider image sets of differentially $d$ -uniform maps of finite fields. We present a lower bound on the image size of such maps and study their preimage distribution, by extend…
